Abstract (en)
[origin: WO2012059156A1] The present invention pertains to the use of cationic surfactants corresponding to formula (I): in which R is an alkyl or alkenyl group containing II carbon atoms, Rl and R2 independently represent hydrogen or C1-4 alkyl, R3 is a C1-4 alkyl group, R4 is hydrogen or methyl, A is a linear or branched C2-6 alkylene group, n is a number from 1 to 25, and X is halogen or alkyl sulfate. Compounds of formula (I) are useful as emulsifiers for aqueous microemulsions containing terpenes.
